Vrc Rear Panel; Network Interface Controller - Avaya Media Processing Server 1000 Hardware Installation And Maintenance

Multiple sources can be specified for both REFCLK_A and REFCLK_B in the synclist section of the
TMS.cfg file. Clock monitoring and selection provides several prioritized layers of redundancy so
that even multiple failures are compensated for by switching to other clock sources.
The VRC rear panel has two BNC connectors (EXT CLK A and EXT CLK B) for connecting to
external timing sources.
Caution:
These connections are for proprietary use by Avaya personnel only. Do not connect to these
BNC connectors.

VRC Rear Panel

The VRC rear panel contains controls, indicators, and connectors that are mainly used for
maintenance and diagnostics. See

Network Interface Controller

Each VRC in the system can contain one or two NICs (primary and secondary). If two NICs are
used in the chassis, a midplane board is installed over the backplane connector of the NIC slot. The
midplane effectively splits the slot, providing separate connectors for each NIC. The two connectors
on the midplane board are logically assigned slots 7 (primary) and 8 (secondary) for addressing.
